- Vitalik proposes RISC-V to replace EVM for better efficiency.
- Aim for improved execution while keeping smart contract compatibility.
- Currently under review with potential long-term implications.
Vitalik Buterin, co-founder of Ethereum, proposed on April 20, 2025, to replace Ethereum’s Virtual Machine (EVM) with RISC-V on the Ethereum Magicians forum, suggesting improved execution efficiency and maintaining backward compatibility.
The proposal matters as it aims to resolve a primary scaling bottleneck in Ethereum, potentially affecting future upgrades. Initial market reaction shows ETH’s slight dip, reflecting cautious investor sentiment.
Vitalik Buterin’s proposal to swap Ethereum’s Virtual Machine (EVM) with RISC-V marks a significant potential shift in Ethereum’s architecture. By suggesting RISC-V, Buterin aims to address existing performance bottlenecks and enhance simplicity.
“It [RISC-V] aims to greatly improve the efficiency of the Ethereum execution layer, resolving one of the primary scaling bottlenecks, and can also greatly improve the execution layer’s simplicity – in fact, it is perhaps the only way to do so.” — Vitalik Buterin, Ethereum Magicians Forum
The announcement prompted discussions among Ethereum developers regarding the feasibility and implementation of such a change. Buterin emphasized maintaining backward compatibility with existing contracts, ensuring a smooth transition as the proposal develops.
The immediate market reaction saw ETH’s price dip by approximately 1%, reflecting investor caution as the proposal enters the exploration phase. Despite this, no drastic financial shifts or impacts on other cryptocurrencies have been witnessed.
Implementation of RISC-V could enhance execution layer efficiency significantly, especially beneficial for zk-EVM proof generation. Discussions also highlighted the potential challenges with existing validator hardware, typically optimized for x86/ARM architectures.
Past upgrades, like Ethereum’s switch to Proof-of-Stake, suggest that such radical proposals may lead to extended speculative periods and multi-year implementation timelines. Nervos Network’s adoption of RISC-V is referenced as a precedent, supporting its feasibility.
Insights indicate potential technological shifts if RISC-V is integrated, offering a 100x speedup in zk-EVM operations. However, these outcomes remain speculative, pending community reviews and further technical assessments on Ethereum’s forums.
